AC E'TYLEN E-GAS G EN ERATO R.

SPECIFICATION forming part of Letters Patent No. 655,487, dated August7, 1900-.

Application filed June 8, 1900- Serial No. 19,582- (No model.)

To all whom it may concern.-

Be it known that I, IsAAc LEONARD HAR- MS, a citizen of the UnitedStates, residing at Jacksonville, in the county of Duval and State ofFlorida, have invented certain new and useful Improvements inAcetylene-Gas Generators, of which the following is a specification.

My present invention relates to improvements in the feeding device of myLetters Patent No. 637,252, dated November 21, 1899, and my applicationfor Letters Patent filed January 29, 1900, Serial No. 3,086.

In the accompanying drawings, Figure 1 is a general view of agas-generator, partly in section, showing my improvements on line A B.Fig. 2 is a similar view at right angles to Fig. 1 and showing myimprovements on line 0 D. Fig. 3 is an enlarged side view of my improvedhanging-strips with pulleys at tached. Fig. 4. is a front view of Fig.3. Fig. 5 is an enlarged interior View of the barrel and disks on themotor-shaft for moving the improved chain-belt floor. Fig. 6 is acrosssection-of same, showing channel-guides in which one of the disksis confined. Fig. 7 is a piece of the chain-belt floor laid flat,showing the fastening links and pins on the under side; and Fig. 8 is alarger view of one link for fastening the flat plates of the chain belttogether.

Similar figures refer to similar parts in the several views.

Features already patented and shown in my former application arereferred to by letters.

a is the gasometer=casing,and b the gasometenbell, through the middle ofwhich stands the carbid-chamber a. At the bottom of the carbid-chamber cis located the mechanism for discharging the carbid into the Watertankd. This mechanism is the immediate subject of my present application andconsists of three or more hanging-strips 1, extending across the fullwidth of the opening into the water-tank at the bottom of thecarbid-chamber working loosely side by side on a fixed pin 2, eachhanging-strip having a small roller pulley 3-,working on an idle axle=pin 4, near its bottom edge, in suitably-arranged wire journals 5,fastened to the hanging-strips, (shown in Figs. 3 and 4,) and anendless-chain-belt moving floor 6, operated by two disks 7, composingthe two ends of a barrel-drum 8, fastened securely to the mo tor-shaftM.

In my former applications I considered it expedient to operate thechain-belt moving floor by means of sprocket-wheels. Thesesprocket-wheels necessitated openingsin the floor of the chain toreceive the sprockets. Experiment has proved that sprocket-wheels areentirely unnecessary and that plain disk pulleys fastened to amotor-shaft develop sufficient friction when the chain belt envelops thedisks to the extent shown on my drawings to operate it and to dischargecarbid into the water-tank as effectually as the former methods; butsprocket-wheels also served to guide the belt uniformly in its travel,and their absence must be compensated for in this re spect. This isaccomplished by the channelguides 9, consisting of narrow flat strips ofmetal soldered to the under side of the plates composing the chain belt6 in two parallel rows opposite to each other, with their meet= ing endsbent outward, as shown in Fig. 5, and just far enough apart to admit oneof the disks 7 to pass between them. One such channel is sufficient forthe guidance of the belt. The chain belt 6, composed of transverse flatplates, is held together by pins 10, soldered near the edge of eachjoint, each pair of pins being secured by a link 11, Fig. 8. There aretwo links to each joint. The chain belt 6 also passes over two smallerdisks 12, composing the two ends of a barreldrunl-which is fastened onan idle shaft 13. The descending convex surface of the chain belt 6comes intofrictional contact with the pulleys 3, fastened to thehanging-strips 1, as shown in Fig. 3, and when carbid is discharged intothe water-tank d the pulleys 3 are pushed away from-the chain belt bythe car-bid in its passage over the descending part of the belt. Thusthe carbid falls into the water-tank d from between two revolvingsurfaces.

The motive power which operates the mech anism of the carbid-feedthrough the medium of the shaft M is derived from the Weight W, Fig. 2,which is fully treated of in my said Letters Patent No. 637,252, datedNovember 21, 1899, and my application for Letters Pat= too ent filedJanuary 29,1900, Serial No. 3,086. A detailed explanation of theoperation of an entire acetylene-gas generator is therefore unnecessary.

Having thus described the nature of my invention, whatI claim as new,and desire to secure by Letters Patent, is

1. In an acetylene-gas generator in combination with a water-tank and acarbid-cham' her, the h. nging-strips 1 and the roller-pulleys 3fastened thereto and working idly near the lower extremity of saidhanging-strips and forming a part thereof for controlling the carbid inits delivery into the water-tank, said hanging-strips Working looselyside by side on the fixed round bar 2 in sufficient numbers 'to'extendacross the full width of the opening into the'water tank at the bottomof the carbid-chambersubstantially as shown.

2. In an" acetylene-gas generator in'combination with awater-tank and acarbid-chamher, the chain belt moving floor 6 for feeding the carbidinto the Water-tank, said chain verse plates, the pins 10 fastened tothe under side of the plates, the links 11 encompassing each pair ofpins and holding the plates together in an endless belt, thechannel-strips 9 fastened to the under side of the plates 6 with theirmeeting ends bent outward in two parallel rows, the two disks 7 fastenedto a motor-shaft for operating said belt, one of said disks Working inthe channel formed by the parallel strips 9 for the purpose of guidingthe belt uniformly, the small disks 12 and the idle shaft 13 to whichsaid disks are fastened and over whichv the chain belt works looselysubstantially as shown'and described.
